2.Main Features of Sodium Hydrosulfite:

It is a versatile chemical that's used in the manufacture of a variety of products we all use every day, 

from photographic film to wine; from fine writing papers to leather goods; from colored fabrics to metal recovery.

While the applications for this chemical workhorse are as vast and as varied as the industries that use it, 

in most cases, sodium hydrosulfite performs one of the following three roles:

1) As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons

2) As sulfonating agent, hydrosulfite adds sulfur to another chemical compound

3) As cation source, hydrosulfite adds a cation, or sodium, to a product system

5.FAQ

1)How many tons does your factory  can supply each moth?

  30000tons/month

2)How to quarantee the quality of the products?

  you can arrange SGS&BV or other quality inspection.

3)How many days you need to pepare the cargo after we made the order?

  within 30 days.

 

4)how about your packing?

  My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag. 

 

5)how long time you can make the shipping?

  We can make the shipping within 5-10day after confirm the order. 

 

6)why you buy from me?

  We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.

Q:What inorganic salts and trace elements are there in rice?
Sodium (2.40 mg) of copper (2.30 micrograms) of copper (2.10 mg) of copper (1.10 mg) of zinc (1.45 mg) of copper (2.40 micrograms)
Q:What is inorganic salt
Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salt ions in the body fluid regulate the permeability of the cell membrane, control the water, maintain normal osmotic pressure and acid-base balance, and help transport the general element to the body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiologic functions, which are constituents of enzymes that make up enzymes, hormones, vitamins, proteins and nucleic acids, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.
Q:After a lot of sweating, the amount of drink with inorganic salt drink right?
It is best to drink this kind of drink, which contains sodium and potassium, and when the body after a lot of exercise will consume a lot of potassium, leaving the body feel weak, this drink can quickly add the body Electrolyte, need to note that before the exercise 1-2 hours, during exercise and after exercise have to drink
Q:what is the function of salts in DNA extraction?
DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.
Q:Chemistry help! physical and chemical properties of salt and sugar!?
Salt: inorganic, ionic bond, soluble in water (ionizes); forms a crystal lattice structure as a solid. Sugar: organic compound, mostly covalent bonds, also soluble in water but does not ionize, can be burned, tastes good (just kidding).
Q:Minor inorganic salts are needed for these functions.?
its not a so try b or c those 2 are the most likely to be the right answers
Q:Inorganic salt effect
1. constitute the body tissue material .2. Regulate the physiological function .3. To participate in the regulation of body fluid balance and maintain the body's acid-base balance .4 cells of some complex compounds of the important components
Q:anybody here knows the difference of organic iron salt (ex. F.gluconate) vs inorganic (ex. F.sulfate)?
It it's organic, then the anion (the negative ion) is the conjugate base of an organic acid. If it's inorganic, then the original acid was inorganic (like H2SO4 making sulphates).
Q:Each of the fallowing is an example of an inorganic compound except one? A)water. B) bases). E)enzymes. D)salt?
anything which contain carbon is organic. so enzyme is the odd one out.
Q:Cells in the water, inorganic salts, protein, lipid
Plus a "so" on the right, because there are many other compounds in the cell
